Tokenized US T-bills reach all-time high market cap of $15B

Tokenized US Treasury products have reached a significant milestone, surpassing $15 billion in total on-chain market capitalization as of May 2026. This figure represents a threefold increase from the $5 billion recorded just 14 months prior, signaling rapid institutional adoption of blockchain-based financial instruments. Data from rwa.xyz indicates that by August 2026, the sector grew further to $16.16 billion across 85 distinct assets held by nearly 63,000 participants. Market leadership is highly concentrated, with five major products—including Circle’s USYC, BlackRock’s BUIDL, Franklin Templeton’s BENJI, and Ondo’s USDY—accounting for approximately 71% of the total market share. These assets provide institutional investors with traditional yields of roughly 3% APY while leveraging blockchain rails for near-instant settlement and enhanced composability. The shift away from legacy clearinghouses allows for efficient collateralization in DeFi protocols and streamlined cross-party transfers. However, the high concentration among a few issuers introduces systemic risk, as regulatory actions against any single provider could significantly impact the broader ecosystem. With an average position size exceeding $250,000, the market remains primarily an institutional domain with limited retail liquidity.
